Abstract
An anti-skid control method for an anti-skid control device comprising two pressure medium lines installed between the master cylinder and the return pathway of the pressure medium with an inlet valve, selector valve, and discharge valve arranged in series in each of the two pressure medium lines, a front wheel brake being connected between the inlet valve and the selector valve of each pressure medium line and a diagonally opposite rear wheel brake being connected between the same selector valve and the discharge valve of that pressure medium line, and a control circuit which controls the front and rear wheel brake pressures through the pressure medium lines. The rotational speeds of each front and rear wheel are determined. The state of traction of each front and rear wheel is judged by the control circuit. The appropriate inlet valve, selector valve, discharge valve and combination thereof are activated to control locking and slippage of each front and rear wheel. In addition, the control circuit opens the inlet valves when the selector valves open to increase the brake pressure of the rear wheels to compensate for the accompanying reduction in pressure of the front wheels.
